System Concepts System Integrated set of components Interact to achieve a particular function or goal. They have boundaries, outputs and inputs, methods of converting inputs into outputs, and system interfaces. They are composed of interrelated and interdependent subsystems.

System Concepts System Boundaries: Subsystems: System boundary defines its scope of activities It delineates an area of responsibility Subsystems: A system can have numerous subsystems. Each of which has elements, interactions and objectives. In business system, various functions are subsystems.

System Concepts Inputs and outputs A system or subsystem are organized to produce outputs from inputs with some value or utility. Example: A training program should produce trained employees with certain skills, knowledge, or behavior from its inputs—untrained employees.

Typical Subsystem- An example INPUT Students without computer literacy OUTPUT Students with Programming Skills Subsystem A Subsystem B Introduction to Data Processing Students with Computer Literacy C Programming O/p From A I/p to B
